Applies an axial align relationship between two parts in an assembly.

You can apply an axial relationship between two cylindrical axes, a cylindrical axis and a linear element, or two linear elements. For example, you can apply an axial align relationship between a cylindrical face on the part you are positioning (A) and a cylindrical face on a part already in the assembly (B).

You can specify whether the rotational axis is locked or unlocked. When you set the Lock Rotation option on the command bar, the rotational orientation is fixed at a random location. This option is useful when the rotational orientation of the part is not important, such as placing a bolt into a hole.

When you set the Unlock Rotation option, you can apply another assembly relationship to control the rotational orientation of the part. For example, you can apply an angle relationship.

You can use an axial align relationship to position a part with respect to an element that is in a part, subassembly, or an assembly sketch.
